1. Product description

Rayson LevelShield SL120 is a solvent-free, two-component, self-smoothing epoxy floor system that delivers a seamless wearing surface with medium to heavy chemical resistance and high mechanical strength.

LevelShield SL120 flows out under trowel, notched rake or roller into a seamless, self-smoothed wearing surface — the standard answer where roller-applied coatings are not enough and a level, joint-free floor is required. Solids content is 100% in both parts, so what goes down is what cures.

2. Recommended uses

  • Areas requiring resistance to mechanical loading and abrasion
  • Pharmaceutical facilities and clean rooms
  • Warehouses, storage areas and loading bays
  • Assembly halls, plant rooms and garages
  • Production areas and maintenance workshops

3. Suitable substrates

  • Mechanically prepared concrete (minimum 28 days old, moisture content below 5%)
  • Substrate pull-off strength above 1.5 N/mm² after preparation

4. Key properties

  • 100% solids, solvent-free — install in enclosed areas without solvent odour
  • Self-smoothing application gives a seamless, level wearing surface
  • Medium to heavy chemical resistance with high compressive and abrasion performance
  • Durable, easy-to-clean finish with excellent impact resistance
  • Chemical resistance
  • Abrasion resistance
  • Hygiene / washdown
  • Low odour

6. Technical data

Surface preparation Substrate must be sound, clean and free of oil, grease, laitance, loose material and bond-inhibiting contaminants. Prepare concrete mechanically (captive shot blasting, milling or diamond grinding); remove weak concrete, open blowholes and voids, and reinstate imperfections with a suitable Rayson repair product. Vacuum all dust. New concrete should be at least 28 days old.
Mixing / dilution Two pre-weighed parts, mix ratio 4:1 (A:B) by weight; mix mechanically for at least 2–3 minutes; pot life up to 20 minutes at 28 °C
Application method Steel trowel, Notched rake, Squeegee and roller, Spike roller to de-aerate
Coverage Approximately 1.6–2.0 kg/m² as a self-smoothing wearing coat, subject to filling grade, porosity, level variation and wastage
Application conditions Minimum substrate temperature 5 °C; substrate moisture content max 5%; minimum mixing temperature +10 °C; cure between +10 °C and +35 °C; prepared substrate pull-off strength above 1.5 N/mm².
Drying & curing At +20 °C: foot traffic 24 h, light traffic 4 days, full cure 7 days. At +30 °C: foot traffic 18 h, light traffic 2 days, full cure 5 days. Recoat window 24 h–2 days at +20 °C (16 h–1 day at +30 °C)
Recoat interval At +20 °C, 24 hours minimum to 2 days maximum; at +30 °C, 16 hours minimum to 1 day maximum.
Film / thickness Self-levelling body coat; nominal thickness set by application rate.
Pack sizes Part A 16 kg / Part B 4 kg per set
Storage Up to 12 months at 5–25 °C in unopened original packaging; protect from direct sunlight.
Shelf life Approximately 12 months unopened, in a cool area.

8. Recommended system

Self-levelling production floor

  1. Mechanically prepare the slab and repair defects with Rayson PatchBond TX80
  2. Prime with Rayson PrimeBond E20
  3. Apply Rayson LevelShield SL120 self-smoothing wearing coat and spike-roll to de-aerate

9. Limitations

10. Health & safety

Two-component product. Wear gloves, eye protection and suitable respiratory protection where ventilation is limited. Avoid skin and eye contact. Keep out of reach of children. Consult the Safety Data Sheet (in preparation) before use.
